The 327th Star Corps was deployed for the first time at the First Battle of Geonosis and remained active all the way to the last days of the Clone Wars. Jedi GeneralAayla Secura was assigned to the Corps after her mission to Hypori, which took place four months into the war. Due to his ARC training, Clone Marshal Commander Bly had misgivings about Secura's Jedi way of doing things, but over time he came to understand her strategies, and the two forged a close relationship.[1]

As the 327th pushed through the planet's southern hemisphere, Bly received Order 66 via a top-secret channel. Order 66 branded Aayla Secura and the rest of the Jedi in command of the corps as enemies of the Republic. When Aayla was distracted by a low-flying bird, Bly and his lieutenants poured blaster fire into their Jedi General, ensuring Secura's death with multiple shots to the body and head.[4][6] The 327th continued to faithfully serve the Empire after its creation.[7]
